MOREThe Westlake University team has developed a new optical fiber spring sensor with a detection limit of picobarn, which may be used to discover microscopic physical phenomena.
Spring scale is a macroscopic force meter, which is often used to weigh various fruits, vegetables, and commodities. If the size is reduced to the micro-nano scale, is it possible to calibrate and "weigh" tiny forces like a spring scale?This requires a significant reduction in the detection limit of the sensor, placing extremely high demands on the precision of the device. In previous studies, ...

MOREQiu Min's team at Westlake University: The influence of film thickness of amorphous Si thin film on laser-induced periodic structure
Research backgroundIn 1947, scientists at Bell Labs invented the world's first transistor, which triggered a revolution in microelectronics technology and profoundly changed the way of life around the world. As electronic devices become increasingly miniaturized, finding a simple, fast, and low-cost method of manufacturing micro-nano components has become a huge challenge. Although traditional ...
MOREDevelopment of fiber-optic endface-integrated superstructured surface electro-optic modulators by Min Qiu's team at School of Engineering, Westlake University.
Electro-optical modulator is one of the core devices in the field of optical communication. By applying an external electrical signal, the amplitude, phase, polarization and even frequency of the light wave are changed, so as to load the external modulation signal onto the light wave and realize the conversion of electro-optical signals. Traditional on-chip integrated electro-optical modulators...
